Brief Introduction
The Vchung 2x100G QSFP-DD CWDM4 optical transceiver transmits data over single mode fibre at a distance of up to 10km. The transceiver operates on 2x 4CWDM wavelengths and works in point-to-point scenario. 2x100G QSFP-DD CWDM4 transceivers have 8 optical lanes that operate at 25Gbps NRZ modulation. They are compliant with QSFP-DD MSA and with the Common Management Interface Specification (CMIS).

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
